Hey guys, I bought a 89si hatch shell and I got this harness with it.

Im trying to figure out what each connector goes to. This is my first obd0 88-91 civic and Im not too familiar with these harnesses. Ive done around 50 obd1& obd2 civics but this is my first obd0.

Any help would be greatly appreciated. Thanks guys

starting from the left

starter spade termial

grounds x2 ring terminals

oil psi yellow/red wire

gray single wire plug is vtec solenoid

2 wire round plug is vtec pressure switch..this could all so be the ect..hard to tell from the pic.

the single wire is for the temp gauge yellow/green wire

the wiring for vtec is for an obd1 vtec solenoid...


im pretty sure i have all this right,its a little hard to see them in the pics...theharness has been opened up and messed with...

I'm wrong on the VTec as it doesn't look like it has it.

The 2nd pic the cut wire is oil psi for gauge light. The 2 wire plug I'm not sure

The 3rd pic the round 2 wire plug should be for the ect sensor. The cut wire is for the water temp (yellow/green)gauge on the cluster. The black wire with the 90 I'm not 100% sure, looks like some one extended the water temp wire,hard to tell
